How to run a script on boot

Hello. I have followed what you taught above. It works! Thank you very much 😍 . But I have one problem that my robot cannot play audio. I try to use in After= and WantedBy=, but it not work.
I use waveshare USB to audio in Jetson Nano. Could you suggest a solution to this issue? 😃
